We stock a wide variety of fasteners ideal for many applications around the home, farm, business, automotive, and in industry. Most of our fasteners have a light Zinc plating over steel giving a more rust resistant finish. We also sell coated and stainless products for additional rust resistance. We stock many grades of fasteners ranging from low carbon steel on up to hardened, heat treated steel. Not all fasteners are applicable for all applications so be certain to test thoroughly and get the opinion of a licensed builder or certified building or structural engineer before relying on these fasteners for any situations where failure would result in damage to property or person.

Hardware Kits: This listing comes with 4 hardware kits, enough to complete the installation. Each kit comes with 4 - 3/8" x 2-1/2" long carriage bolts, 4 - fender washers, and 4 - 3/8" nylon locking nuts. The 2.5" bolts are long enough to go through 2" thick planks which is typical on an open trailer.

IMPORTANT - Most enclosed trailers have 3/4" thick floors. The 2.5" long bolts will work on 3/4" floors but are longer than what is needed. Therefore if you prefer 1-1/2" bolts please message us and we'll be happy to provide the shorter bolts. APPLIES to seller fulfilled orders only.

This tie down attachment has a 6,000 lb. capacity* vertical pull weight rating. To install this attachment requires routing, or cutting a hole in the floor. This recessed d-ring has square holes punched for receiving carriage bolts, providing a smooth and relatively "trip free" surface. The steel attachment is zinc coated to inhibit corrosion. When in use the ring portion raises for application and lies down when not in use, thus creating a flush surface. This tie down attachment is plenty strong and is able to receive multiple tie-down straps simultaneously. To obtain maximum strength it is recommended to install these d-rings with bolts, lock nuts, and fender washers. For installation purposes it is easiest to cut a template and then transfer to the desired location.

* RATED CAPACITY: Also known as "assembly capacity" or "break strength" is the minimum load a complete assembly can withstand before failure in a laboratory pull test when the product is new. ***WORKING LOAD LIMIT: The maximum load weight a tie-down should be subjected to during normal use. To assist in making the proper tie-down choice the Federal D.O.T. requires the W.L.L. to be 1/3 of the Rated Capacity.

Features

4 complete sets of D-rings, backing plates and 2 1/2" hardware kits. Both components are zinc coated to inhibit rust and corrosion. The d-rings have square holes punched for receiving carriage bolts, providing a smooth and relatively trip free surface. When in use the ring portion raises for application and lies down when not in use, thus creating a flush surface. It is plenty strong and is able to receive multiple tie-down straps simultaneously.

Each D-ring has a 6,000 lb straight pull capacity. RATED CAPACITY: Also known as assembly capacity or break strength is the minimum load a complete assembly can withstand before failure in a laboratory pull test when the product is NEW. WORKING LOAD LIMIT: The maximum load weight a tie-down should be subjected to during normal use. To assist in making the proper tie-down choice the Federal D.O.T. requires the W.L.L. to be 1/3 of the Rated Capacity.

INSTALLATION - these D-rings require routing, or cutting a hole in the floor. We recommend creating/cutting a template and then transferring to the desired location. If you use a 3 hole saw, the d-ring will fit without any further work. Better fit - use a 2-1/2 hole saw then jigsaw the flat edge and then bevel the edge with a wood hasp to create a snug fit.

Carriage Bolts are designed to fasten a wooden face to either a wood or metal frame. Its flat head is designed to eliminate the need for a washer and provide a semi-flush finish to applications. The square underside of the head is self locking to eliminate spinning and the need for a driving tool. The zinc plating is rust resistant and provides a beautiful, consistent finish; but, may not work for all exterior projects.

Carriage Bolt 18-8 Stainless Steel 5/16"-18 x 2-1/4" Qty-25

Features

A carriage bolt has a domed or countersunk head and the shank is topped by a short square section under the head of the bolt.

The square section grips into the part being fixed, preventing the bolt from turning when the nut is tightened.

Carriage bolts are often used to fasten wood panels or board to masonry or to one another.

The square shank of the bolt allows it to lock into place when inserted into a round hole in wood or a square hole in a metal strap, the unthreaded square shank pulls into the wood creating a tight connection.

Round domed head with square neck Package includes ten each of bolts, hex nuts & washers Zinc plated for corrosion resistance Suitable for indoor or outdoor use BCP Fasteners are always backed by a 100% satisfaction guarantee A carriage bolt, coach bolt or round head square neck bolt is a form of bolt used to fasten metal to wood or wood to wood.

Carriage bolts are distinguished from other bolts by its shallow mushroom head and the portion immediately beneath the head is formed into a square section. This makes the bolt self-locking when placed through a square hole in a metal strap, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or wrench, working from one side. The head of a carriage bolt is usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank.

Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them to bare timber, the squared section giving enough grip to prevent rotation.

Carriage bolts are extensively used in security fixings, such as the Brenton Bolt where the bolt must only be removable from one side. The smooth domed head and square nut below prevent the carriage bolt from being unlocked from the insecure side.
